FIELD OF THE INVENTION

This application concerns certain 2-phenylamino-6-aryl amino-, 6-aryloxy-, and 6-arylthio-purines, -azapurines and -deazapurines. These compounds are non-nucleoside reverse transcriptase inhibitors and have potential as anti-HIV treatment.

BACKGROUND OF THE INVENTION

Human Immunodeficiency Virus (HIV) presents a public-health and social catastrophe too well known to require documentation. One therapeutic approach to HIV has been inhibition of the viral RNA-dependent RNA polymerase; this enzyme is frequently referred to as “reverse transcriptase,” abbreviated “RT.” The first RT inhibitors were nucleoside analogs such as AZT and dd. Although such nucleoside RT inhibitors were frequently effective against the wild-type virus, any single-drug treatment has been hobbled by the virus's ability to readily produce drug-resistant mutants. This has led to an intense search for non-nucleoside RT inhibitors (“NNRTIs”) which are both effective and capable of retaining their effectiveness despite drug-resistance mutations. A recent review of NNRTIs can be found Balzarni, J., 2004, Cur. Top. Med. Chem. 4, 921-44 (Erratum ibid. 4, 1825).

Four leading NNRTI are: 1) Efavirenz (4S)-6-chloro-4-(cyclopropylethynyl)-1,4-dihydro-4-(trifluoromethyl)-2H-3,1-benzoxazin-2-one; 2) Capravirine: 1H-Imidazole-2-methanol, 5-((3,5-dichlorophenyl)thio)-4-(1-methylethyl)-1-(4-pyridinylmethyl)-carbamate (ester); 3) Etravirine (TMC 125): 4-((6-amino-5-bromo-2-((4-cyanophenyl)amino)-4-pyrimidinyl)oxy)-3,5-dimethyl-benzonitrile; and 4) Rilpivirine (TMC-278): 4-([4-[(4-[(1E)-2-cyanoethenyl]-2,6-dimethylphenyl)amino]-2-pyrimidinyl)amino]benzonitrile. Rilpivirine and Etravirine belong to a subclass of NNRTIs called diarylpyrmidines (“DAPY”). For a review of these DAPY NNRTIs see Ludovici, D. W., et al., 2002, Bioorg. Med. Chem. Lett. 11, 2235-9. An extensive patent literature also exists for DAPY. U.S. Pat. No. 6,197,779; WO 00/27850; WO 2003/016306; and WO 2004/069812, all assigned to Janssen Pharmaceuticals.

Diaryl compounds similar to Etravirine and Rilpivirine where the pyrimidine moiety is replaced by a purine are described in WO 2005/028479, which also is assigned to Janssen.

The mixture was stirred at 65° C. for an additional 2 h and cooled to room temperature. The reaction mixture was concentrated in vacuo to one third of its original volume and stored at 4° C. for 16 h. The light pink precipitates were filtered, washed with an ice cold H₂O (5 mL), and dried under high vacuum for 16 h. The precipitates were placed in Soxhlet extractor and refluxed with methanol (200 mL) for 24 h. The methanol was concentrated to give 13.3 g (56%) of 2-amino-3,7-dihydro-pyrrolo[2,3-d]pyrimidin-4-one as a light pink solid.

Step A2

Scheme 1 illustrate the synthesis of 9-deazaguanine by starting with commercially available 2-amino-6-methylpyrimidin-4(3H)-one and nitrated with nitric acid followed by treatment of the nitrated product with N,N-dimethylformamide dimethyl acetal (DMF-DMA) to afford the corresponding 2-(dimethylamino)methyleneimino derivative.

Reductive cyclization with sodium hydrosulfite followed by de-protection with 3M NaOH and de-benzylation with Pd/C and NH₄CO₂H afforded 9-deazaguanine.

Scheme 2 illustrates the 3 different pathways which provide the various substituted 9-deazapurines. Other products are synthesized by analogous methods, which a person skilled in the art could formulate, based on the reaction sequences given above. In certain cases, the person skilled in the art would see that protecting groups might be necessary. The synthetic scheme can be summarized as follows.

Benzylation of 9-deazaguanine followed by chlorination with POCl₃ gives the chlorinated 9-deazapurine product. This chlorinated intermediate can either be coupled with R2 (pathway 1) followed by diazotization with t-butyl nitrite; displaced with F; coupled with R3 and de-benzylated to give the product; or it can undergo pathway 2, which is diazotization with t-butyl nitrite in the presence of antimony chloride followed by coupling with R2 and R3, followed by de-benzylation to afford the final product. Alternatively, pathway 3 provides for de-benzylation of the dichloro-9-deazapurine followed by the coupling with R2 and R3 respectively to provide the various substituted 9-deazapurine.

Biological Activity Inhibition of HIV-1 Reverse Transcriptase

Numerous compounds were screened for inhibitory activity against human immunodeficiency virus type 1 (HIV-1) using a high throughput cell-based assay using HIV-1 expressing firefly luciferase as a reporter gene and pseudotyped with vesicular stomatitis virus envelope glycoprotein (VSV-G). Experimental procedures were essentially as described by Connor et al. in Journal of Virology (1996), 70: 5306-5311 (Characterization of the functional properties of env genes from long-term survivors of human immunodeficiency virus type 1 infection), and Popik et al. in Journal of Virology (2002), 76: 4709-4722 (Human immunodeficiency virus type 1 uses lipid raft-co-localized CD4 and chemokine receptors for productive entry into CD4+ T cells). It should be particularly appreciated that the virus contains two introduced mutations in the RT gene (K103N and Y181C, created by PCR mutagenesis) that render the virus highly resistant to current non-nucleoside HIV-1 drugs. Virus stocks were generated by cotransfection of plasmid DNA encoding VSV-G with vector pNL4-3Env(−)Luc(+) into 293T cells. Sixty-four hours after transfection, virus-containing medium was collected by centrifugation and stored frozen at −80° C.

HeLa cells were infected with the VSV-G pseudotyped virus in the presence of screening compounds in a 384-well microtiter plate format. Forty-eight hours after initial infection, lysis buffer and Luciferase Assay Reagent (Promega) was added to the cells and luciferase activity was determined by counting the resultant luminescence using a LJL luminometer. Since the luciferase gene is carried in the virus genome, its expression level directly reflects the virus replication level in the presence of a compound.

To evaluate the activity of the compounds against wild type HIV-1, the HeLa-JC53 cell line that expresses high levels of CD4 and CCR5 (see e.g., Platt et al. in Journal of Virology (1998), 72: 2855-2864: Effect of CCR5 and CD4 cell surface concentrations on infection by macrophagetropic isolates of human immunodeficiency virus type 1) was modified by isolation of a stable cell line that expresses luciferase under the control of the HIV-1 promoter (long terminal repeat, i.e., LTR). HIV-1 infection of this cell line stimulates the transcription of luciferase from the HIV-1 promoter and the luciferase gene expression level is proportional to the level of virus replication (Harrington et al. in Journal of Virology Methods (2000), 88: 111-115: Direct detection of infection of HIV-1 in blood using a centrifugation-indicator cell assay; and Roos et al. in Virology (2000), 273: 307-315: LuSIV cells: a reporter cell line for the detection and quantitation of a single cycle of HIV and SW replication). Procedures for virus infection, compound testing and luciferase activity determination were the same as for the VSV-G pseudotyped HIV-1.

Two approaches were used to evaluate the cytotoxicity of the positive compounds discovered in the HIV-1 virus assays. The first approach employed another modified HeLa-JC53 cell line that constitutively expresses high level of luciferase without virus infection. The level of luciferase expression in these cells served as an indicator for cell replication in the presence of the compounds. Procedures for compound testing and luciferase activity determination were the same as for the virus infection tests. The other toxicity assay utilized HeLe-JC53 cells and a commercially available MTS assay kit (Promega) that measures the mitochondria function of the cells.
